Description (last modified by )
This ticket summarizes the work done in the ACTIS project.
The main goal of this project is to enhance the decoding part of Sage, doing the following:
- propose a new API to manage code families
- propose a new API to manage multiple encoders for a given code family (i.e multiple message spaces)
- propose a new API to manage multiple decoding algorithms for a given code family
- implement numerous code families, alongside their encoders and decoders
The following tables gives a quick access to all tickets related to the project:
- The first table contains references to every ticket adding major features, like new code families, decoders...
- The second table contains references to every small ticket: bug fixes, minor quality of life upgrades, etc
- The last table contains references to every ticket which has been positive reviewed and/or closed.
The Nature
column gives the "type" of the ticket :
Structure
means it's a structural ticket, which does not require any knowledge in coding theory. It will be for tickets which introduce new mechanisms in the API.Cleanup
means it's a ticket that refreshes old existing code of the coding library, and/or documentation. It does not require any knowledge in coding theory.Content
means it adds new mathematical content (code families, decoding algorithms, ...) to Sage. Some knowledge on the topic might be useful for these tickets.Documentation
means it's a ticket which adds some new documentation in the library. It does not require any particular knowledge in coding library, nor being familiar with our code.Enhancement
means it's a ticket which makes some existing code better, either in matter of speed or design.
